Other claims from this paper (16)
- Intervention effect Under normal nitrogen, FACE significantly increased rice root biomass, volume and length.
- Intervention effect Under normal nitrogen, FACE significantly increased rice root diameter.
- Intervention effect Under normal nitrogen, FACE significantly increased barnyardgrass root biomass, volume and length.
- Intervention effect Under normal nitrogen, FACE significantly increased barnyardgrass root diameter.
- Association Rice had a stronger carbon dioxide root response than barnyardgrass under normal nitrogen.
- Intervention effect At low nitrogen, FACE did not significantly promote rice growth because of nitrogen stress.
- Intervention effect At low nitrogen, barnyardgrass growth increased significantly under FACE.
- Intervention effect Elevated carbon dioxide significantly reduced root nitrogen concentration in rice.
- Intervention effect Elevated carbon dioxide significantly reduced root nitrogen concentration in barnyardgrass.
- Intervention effect Root carbon concentration did not change markedly under elevated carbon dioxide.
- Intervention effect Root carbon concentration did not change markedly under elevated carbon dioxide in barnyardgrass.
- Intervention effect Elevated carbon dioxide increased root carbon-to-nitrogen ratio in barnyardgrass.
- Intervention effect Elevated carbon dioxide markedly decreased rice root hair number and per-unit dry root weight.
- Intervention effect Elevated carbon dioxide markedly decreased barnyardgrass root hair number and per-unit dry root weight.
- Mechanism The authors suggest reduced root hairs and per-unit dry root weight may explain lower root activity under FACE.
- Mechanism The authors suggest reduced root hairs and per-unit dry root weight may explain lower barnyardgrass root activity under FACE.
